A pollen succession from the Czarnucha section (Augustów Plaine) and its significance for the Lower Pleistocene stratigraphy of northeastern Poland
Journal Title: Biuletyn Państwowego Instytutu Geologicznego - Year 2009, Vol 435, Issue 435
Abstract
Palynological analysis was used to study deposits in the Czarnucha section at the depth of 93.10–126.00 m, where 26 Local Pollen Assemblage Zones (L PAZ) have been distinguished within the pollen succession. The zones are a basis for palynostratigraphic considerations and allow for a reconstruction of the vegetation history. The pollen succession recorded in this section provides an evidence of two warm interglacial periods and a number of horizons with pollen flora suggesting a glacial age. The older warm interglacial illustrates a decline of the succession with dominant boreal pollen flora and the presence of [i]Azolla filiculoides[/i] Lam. foss. The younger warm period is characterized by the occurrence of [i]Carpinus [/i]and the development of deciduous forests with abundant [i]Ulmus[/i], [i]Acer[/i], [i]Fraxinus [/i]and [i]Corylus[/i]. In the cool interval separating the interglacials, a pollen flora typical of a warm interstadial is observed. The Czarnucha pollen succession and its characteristics allow for a correlation with the Augustów succession.
